Application February 15, 1941, Serial No. 379,038

5 Claims.

My invention relates to an improvement in.

razors, and this application is a continuation-inpart of my priorapplication on Safety razors, Ser. No. 304,556, filed November 15, 1939.

The object of my invention is to improve the guard of a safety razor tofacilitate the shaving action by providing for freedom of movement ofthe razor in all directions.

A further object is to incorporate in the safety razor a razor guardprovided with a plurality of spheres to roll in operation and eliminateraking and scraping, and to be used in a single and double edged razor;and a razor blade to be used in both razors in combination with theguard which guard plate is provided with slots to allow the flow of cutstubble and lather to flowthrough to prevent plugging up the razor.

I have illustrated a preferred embodimentof my invention in theaccompanying drawing, in which:

Fig. 1 is a side view of a single edged razor provided with a singleedged blade and a single edged guard.

Fig. 2 is an end view of Figure 1.

Fig. 3 is an inside view of guard plate, with bed plate and razor bladeremoved.

Fig. 4 is a perspective of bed plate as viewed from underside.

Fig. 5 is a plan view of blade to be used in both razors, single anddoubled edged.

Fig. 6 is an end view of a double edged razor disclosing two blades asshown in Fig. 5, and a double edged guard provided with a plurality ofspheres which may be made of suitable material such as ball bearings,glass, pearls, or any suitable composition.

The drawing illustrates the invention as applied, a specific form ofrazor provided with means to suit a blade and two razors, but it will beunderstood that this invention is not limited to this form but isequally applicable to other forms and shapes, such as single and doubleedged blades to fit razors.

In the drawing, the numeral l designates a guard plate in entirety;numeral I I a seat or channel for spheres; numeral l2 indicates spheres;numeral 13 end guard to retain spheres; numeral I4 indicates key on topof guard plate; l indicates notch on top of guard plate to match therazor blade; l5 indicates slots in guard plate to allow the fiow oflather to go through; numeral ll indicates a hole to allow stud 24 to gothrough; numeral [8 indicates the blade; while numeral l8a indicatessecond blade shown in Fig. 6, to operate the double-edged razor. Numerall9 indicates notches at both ends in the. razor blade; numeral 20indicates a notch in the back of the blade so the blade may be heldrigid at three points; numeral 2! indicates bed plate provided with stud24 and lugs 23. Numeral 22 indicates back shoulder on bed plate; numeral23 indicates lugs on bed plate to register with notches in blade andguard plate to hold same rigid. Numeral 24 indicates clamping" screw inbed plate to screw the handle- 25 on; numeral. 25 indicates the handle.

In operation the razor blade 5 is fitted on the bed plate Fig. 4 sonotches l9 will fit the lugs 23 onthe. bed plate Fig. 4, and thethreaded stud 24 willfit groove 20 to hold same rigid; then the guardplate is slipped on over the threaded stud 24 and notches I5 in theguard plate, and the handle 25 is screwed on to stud 24, and the singleedged razorv and blade is assembled ready as shown in Fig. l and Fig. 2;while the assembly of the double edged razor will be practically thesame'with the exception of adding another bladeprovided with a secondguard to the plates,

The channel II for the balls or spheres I2 is formed in a portion at theedge of the guard plate I0 that is ofiset laterally substantially fromthe major portion of the width of said guard plate, as shown in Figs. 2and 6, with said channel extending lengthwise of the blade cutting edge.The channel H is so positioned that it projects outwardly beyond thefree edge of the bed plate 2| and the cutting edge of the blade. Theballs or spheres l2 in the channel are confined loosely therein free forturning movement in all directions and extend in a straight linelengthwise of the guard plate with portions of the balls projecting fromthe channel H toward the cutting edge of the blade [8 to ride on theskin at the point of cutting and to smooth out the skin foraccomplishing the desired cutting action. The razor may be used in anydesired stroke either at right angles to the length of the blade or inan arcuate or angular movement, the balls or spheres rolling over thesurface freely and providing for a smooth cutting action without pullingof the hairs.

It will be understood that my invention is not limited to any particularconstruction or type of razors illustrated and described, but may beadapted and employed to all forms of razors in which a razor blade maybe used on two razors and a guard provided with a plurality of spheresseated to suit the razor.

Having described my invention, what I claim and desire to secure byLetters Patent is:

and said channel portion projectin outwardly beyond the free edge of thebed plate, and a series of balls confined in said channel andrespectively free therein for turning movement in all directions, saidballs being arranged adjacent the I blade cutting edge and forming aguard therefor and permitting movement of the razor in any directionover the skin.

2. In a safety razor having a guard plate, a bed plate, means forsecuring the bed plate and guard plate together in clamping relationwith lateral edge portions of said plates adjacent each other, and ablade clamped between said plates and having a cutting edge projectingfree of said lateral edge portions, the edge portion of said guard platesubstantially throughout the length thereof being offset laterallysubstantially from the major portion of the width of said guard plateand having a channel in said offset edge portion extending lengthwise ofthe blade cutting edge, and said channel portion projecting outwardlybeyond the free edge of the bed plate, and a series of balls confined insaid channel and respectively free therein for turning movement in alldirections, said balls being arranged adjacent the blade cutting edgeand forming a guard therefor and permitting movement of the razor in anydirection over the skin, said guard plate having a slot therein andextending lengthwise thereof parallel with the channel and adjacent tosaid channel beneath the free cutting edge of the blade for dischargingcut hairs therethrough.

3 A guard plate for a safety razor adapted to receive a blade thereonwith a lateral cutting edge, said guard plate having an edge portionsubstantially throughout the length thereof offset laterally from themajor portion of the width of said guard plate, said offset edge portionhaving a channel therein and extending lengthwise thereof, and a seriesof balls confined in said channel and respectively free therein forturning movement in all directions, said balls forming a guard for theblade cutting edge and permitting movement of the razor in any directionover the skin.

4. A guard plate for a safety razor adapted to receive a blade thereonwith a lateral cutting edge, said guard plate having one edge portiononly thereof substantially throughout the length thereof offsetlaterally from the major portion of the width of said guard plate, saidoflset edge portion having a channel therein and extending lengthwisethereof, and a series of balls confined in said channel and respectivelyfree therein for 1 turning movement in all directions, said ballsforming a guard for the blade cutting edge and permitting movement ofthe razor in any direction over the skin.

5. A guard plate for a safety razor adapted to receive a blade thereonwith lateral cutting edges, said guard plate having each opposite edgeportion substantially throughout the length thereof offset laterallyfrom the major portion of the width of said guard plate, said ofisetedge portion having a channel therein and. extending lengthwise thereof,and a series of balls confined in said channel and respectively freetherein for turning movement in all directions, said balls forming aguard for the adjacent cutting edge of the blade and permitting movementof the razor in any direction over the skin.
